Tesla is pushing a United States appeals court to reinstate a 2016 rule enacting steeper fines for automakers that fail to meet fuel economy targets, Reuters reports.
In January—just days before President Joe Biden took office—the Trump administration delayed the implementation
The Biden administration has promised tougher emissions standards, but it opposes Tesla’s request, saying the the National Highway Traffic Safety Administration (NHTSA) is conducting a review of the Trump administration’s actions, which is expected to take six m onths, according to the report.
Tesla, which first asked the court to reinstate the higher fines March 4, said Monday that the government’s position “ignores the ongoing impacts” on the market for emissions credits, the report said.

Automakers at risk of missing fuel-economy targets can buy credits from competitors that have surpassed the standards, and that has long been a big source of revenue for Tesla. A 2019 deal to pool credits with Fiat Chrysler Automobiles (now Stellantis) in Europe was reportedly worth $2 billion
Fuel-economy fines were first enacted in 1975, and have only been raised once—from $5.00 to $5.50 for every 0.1 mpg over current standards, in 1997. That means they’ve lost nearly 75% of their original value, Reuters
In 2015, Congress ordered all federal agencies to adjust civil penalties for inflation which, in the case of fuel-economy fines, meant an increase from $5.50 to $14 per 0.1 mpg over the limit. The Trump administration lost a court battle in 2018 over an attempt to roll back the fines, and also tried to freeze fines
The Biden administration was expected to act quicker—especially to enforce fines enforcing rules set many years ago—but it may take time to address all of the regulatory damage done by the previous administration.
